Objective Telangiectasias of the lower legs are intradermal dilatations of the subpapillary venous plexus, but their pathophysiology and risk factors are still largely unknown. The purpose of this review is to summarize the current knowledge on the pathophysiology and risk factors for telangiectasias. Methods A systematic review of the literature indexed in Medline completed with textbooks and European phlebology journals from the French, Swiss, and German phlebology societies was performed. Results A multitude of risk factors and several pathophysiological hypotheses, such as reflux, arterio-venous micro-shunts, parietal, and connective tissue abnormalities, are described in the literature...

Objectives To assess the current use of safety checklists among the American College of Phlebology (ACP) members and their interest in implementing a checklist supported by the ACP on their clinical practices; and to develop a phlebology safety checklist. Method Online surveys were sent to ACP members, and a phlebology safety checklist was developed by a multispecialty team through the ACP Leadership Academy. Results Forty-seven percent of respondents are using a safety checklist in their practices; 23% think that a phlebology safety checklist would interfere or disrupt workflow; 79% answered that a phlebology safety checklist could improve procedure outcomes or prevent complications; and 85% would be interested in implementing a phlebology safety checklist approved by the ACP...

Scope Varithena® is a recently approved commercially available drug/delivery unit that produces foam using 1% polidocanol for the management of varicose veins. The purpose of this review is to examine the benefits of foam sclerotherapy, features of the ideal foam sclerosant and the strengths and limitations of Varithena® in the context of current foam sclerotherapy practices. Method Electronic databases including PubMed, Medline (Ovid) SP as well as trial registries and product information sheets were searched using the keywords, 'Varithena', 'Varisolve', 'polidocanol endovenous microfoam', 'polidocanol' and/or 'foam sclerotherapy/sclerosant'...

Objectives Recurrent varicose veins following surgery is a common, complex and costly problem in vascular surgery. Treatment for RVV is technically more difficult to perform and patient satisfaction is poorer than after primary interventions. Nevertheless, traditional vein surgery has largely been replaced by percutaneous office-based procedures, and the patients with recurrent varicose veins have not benefited from the same advantages. In this paper, we propose an endovascular laser treatment that allows reducing the invasiveness and complications in case of SFJ and SPJ reflux after ligation and stripping of the great and small saphenous vein...

Background Recurrent varicose veins occur up to 80% of procedures. The sapheno-femoral junction can be involved in more than 50% of cases. A detailed pathophysiological explanation of the phenomenon is still missing. The aim of the present work is to evaluate the role of femoral vein incompetence as risk factor for sapheno-femoral junction recurrence. Methods Three-hundred-eighty-one patients presenting an incompetent great saphenous vein system and eventually also an incompetent femoral tract (C2-6EpAsdPr) underwent a great saphenous vein high ligation with flush ligation also of the incompetent tributaries along the leg, sparing the saphenous trunk...

Background Although well characterised in adults, less is known about post-thrombotic syndrome in children. In this review, current knowledge regarding paediatric post-thrombotic syndrome is summarised, with particular emphasis on pathophysiology, aetiology, diagnosis and management. Methods A Medline literature review was performed using search terms 'post thrombotic syndrome', 'post phlebitic syndrome', paediatric and children. Relevant articles were identified and included for summation analysis. Results The incident of paediatric venous thromboembolism is rising...

Objectives Joint dysfunction occurs frequently in patients with venous malformations of the extremities. This study aims to describe the risk factors of joint dysfunction in these patients. Method We retrospectively collected clinical and radiological aspects of 168 patients with extremity venous malformations from January 2013 to August 2015. Patients were categorized into "with joint dysfunction" or "without joint dysfunction" groups according to the symptoms. Results Forty-four (26%) patients were assigned into with joint dysfunction group...

Objective To better understand factors that may play a role in the development of varicosities. Methods We induced combined flow-pressure disturbance in the saphenous system of the rat by performing chronic partial clipping of the main branch. Biomechanical and quantitative histological testing was undertaken. Results A rich microvenous network developed. Bloodflow decreased to 0.65 ± 0.18 µl/s (control side, 3.5 ± 1.4 µl/s) and pressure elevated to 6.8 ± 0.7 mmHg (control side, 2.3 ± 0...

Background Leg ulcers are a common cause of morbidity and disability and result in significant health and social care expenditure. The UK National Institute for Health and Care Excellence (NICE) Clinical Guideline (CG)168, published in July 2013, sought to improve care of patients with leg ulcers, recommending that patients with a break in the skin below the knee that had not healed within two weeks be referred to a specialist vascular service for diagnosis and management. Aim Determine the impact of CG168 on referrals to a leg ulcer service...

Background Sclerotherapy has been gaining increased acceptance and popularity as an effective therapy for the treatment of varicose veins. This attention has fed growing interest into the safety and potential complications of this procedure. There is no evidence of pulmonary complications from foam sclerotherapy in humans; however, animal studies have shown possible damage. The aim of this study is to show the changes in rat pulmonary parenchyma after the injection of 1% polidocanol Tessari foam into the peripheral vein using histological analysis of the inflammatory and fibrosis processes...

Background Literature concerning the lower limbs physiological venous haemodynamics is still lacking of reference velocity values and consequent impact on drainage direction. Aim of the present study is to assess the flow velocities in the different venous compartments, evaluating the possible Venturi effect role, thus finding clues for the identification of the physical model governing the flow direction. Methods Thirty-six lower limbs underwent a velocity and diameters echo-color-Doppler assessment in several anatomical point of analysis along both the deep and superficial venous systems...

Forced expiration against an airway obstruction was originally described as a method for inflating the Eustachian tubes and is accredited to Antonio Maria Valsalva (1666-1723). The Valsalva maneuver is commonly applied for different diagnostic purposes. Its use for phlebologic diagnosis is the object this review. Venous reflux is the most frequent pathophysiologic mechanism in chronic venous disease. Reflux is easily visualized by duplex ultrasound when properly elicited, in standing position. A simple way to elicit reflux is the so-called "compression-release maneuver": by emptying the muscle reservoir, it determines a centrifugal gradient, dependent on hydrostatic pressure, creating an aspiration system from the superficial to the deep system...

Introduction Little is known about the anatomic variation and its implication in patients with lower limb deep venous thrombosis (DVT). We studied the clinical presentation, site of thrombosis and risk factors based on the anatomic distribution of lower limb DVT. Methods A retrospective analysis of clinically suspected DVT cases was conducted between 2008 and 2012. DVT was categorized by the location of the thrombosed segment and limb involved. The DVT anatomic segments were assessed according to left-to-right ratio, predisposing factors and clinical presentations...

Introduction Low-flow vascular malformations are congenital abnormalities of the veins, capillaries or lymphatic vessels or a combination of the previous. Compressive garments are frequently used as a first-line treatment option for low-flow vascular malformations of the extremities with the purpose of relieving symptoms. Yet, the benefits and harms of compression stockings remain unclear. Methods A systematic search was performed in MEDLINE, Embase, Cochrane Central Register of Controlled Trials including a hand search for studies measuring the benefits and harms of compression garments in treating low-flow vascular malformations...
